    Background
    
    BMS-708163 is a potent selective and orally bioavailable inhibitor of γ-secretase with IC50 value of 0.3nM [1].The cleavage of amyloid precusor protein APP by γ-secretase causes the production of Aβ40 and Aβ42, which are cytotoxic and cause AD. In vitro assay shows BMS-708163 inhibits the formation of Aβ40 and Aβ42 in H4-8Sw cells. It also inhibits the human recombinant CYPs in vitro with IC50 value of 20μM. Notch receptor is another substrate of γ-secretase. The inhibition of Notch signal pathway results in some side effects. It is shown that the activity of BMS-708163 to inhibit Notch is 190-fold weaker than to APP. In female rats, oral administration of BMS-708163 significantly reduces the production of Aβ in plasma and brain at 10mg/kg and 100mg/kg. In addition, BMS-708163 also reduces Aβ in brain and CSF in male beagle dogs [1].
